ABSTRACT
To evaluate the clinical correlation between the penile size and benign prostatic hyperplasia (BPH) we measured the penile circumference(PC) and length(PL) as the flaccid state in 416 male cases more than 50 old years. PC was measured on the penile groove and PL from upper margin of symphysis pubis to the tip of penile glans. We compared PC and PL with prostatic volume, IPSS symptom score, uroflow and BPH defined by Garraway (1993)(BPH-G). All cases were classified as group I(below 9.0cm : 231 cases), II(above 9.0cm : 185 cases) in PC and A(below 8.0cm . 206 cases), B(above 8.0cm 210 cases) in PL. The ranges of PC and PL value were 6.0- 13.0cm(ave. 9.2) and 5.0-13.0cm(ave. 8.2), respectively. PC and PL values according to presence and absence of BPH-G were 9.3+/-0.8cm, 8.4+/-2.6cm and 8.6+/-1.5cm, 7.6+/-2.6cm, respectively (P<0.05), and PC values in prostatic volume below 30gm and more than 30gm, 8.8+/-l.0cm, 9.5+/-0.7cm, respectively (p<0.05). Among BPH associated factors, only prostatic volume has a correlation with penile size according to regression analysis(<0.05). Prevalence of BPH in group I, II and A, B was 10.4%, 27.09& and 0.49&, 31.4%, respectively(p<0.05). As higher PL or PC, as higher prevalence of BPH. We suggest that prominently large penile size, especially PC may be a possible sign of BPH.
